Filed: 1995-06-30
Abstract: An optical memory (100) in which data is stored in an optical data layer (190) capable of selectively altering light such as by changeable transmissivity or polarization. The data is illuminated by controllable light sources (330) and an array of multi-surface imaging lenslets (210) project the image onto a common array of light sensors (270).

IPC: H05B41/392
Filed: 1995-07-10
Abstract: A servo-amplifier for controlling a high-ohmic low-voltage source controllable between two boundary values of a pulse-width-modulated control signal, in which the input side has a galvanic separation and there is an operating voltage supply for the servo-amplifier. In an isolating transformer (1) for galvanic isolation, a circuit (with the components 4, 5, 6, 7) for finding the average of the pulse-width-modulated control signal for imaging the control signal is connected to a secondary winding (3) and the latter is also involved in a voltage multiplication circuit (17) to provide the operating voltage for the servo-amplifier. The servo-amplifier can in particular be protected against incorrect connection.

Title: Modified sports goal for improving shooting accuracy
Inventor: REILLY FRANCIS J JR
IPC: A63B63/00
Filed: 1997-03-04
Abstract: A modified sports goal is adapted for training a sports player to direct objects into preferred target areas. A modified goalpost frame is formed in the shape of a preferred target area of a standard sports goal. A net is coupled to the goalpost frame. The goalpost and net capture objects, such as hockey pucks, directed into the preferred target area, and allow misdirected objects which otherwise would have been captured by the standard sports goal to pass thereby. In this manner, a participant is rewarded with the feeling of achieving a goal only if the object enters the target areas. Otherwise, the object passes by the goal. This goal reduces the need for goaltenders during practice sessions, mitigating the possibility of goaltender injury and improving the shooter's ability to develop skills.

Title: Fluid Delivery System with Mounting Linkage
Inventor: WARNER ERIC A
IPC: A61M5/142
Filed: 1995-09-07
Abstract: A fluid delivery system in which the pressure platen for a fluid conduit is fixedly mounted to the pump and the pumping mechanism is movable in relation to the platen (32) to control the force exerted on the conduit. A moving system comprising a four-bar linkage (48, 50, 52, 54) retains the movable pumping in mechanism in a predetermined orientation to the conduit through the mechanism's range of movement.  The pumping mechanism  is spring (63) loaded towards the conduit (30). The peristaltic fingers (22) of the pump mechanism are located in guides with the drive means for those fingers rigidly mounted to that guide. Should the movements of one or more fingers through the respective guide be prevented, the drive means will be stopped from movement and the pumping mechanism will stall rather than back off and allow free flow.

Title: Movable sheet for laminar flow and deicing
Inventor: SHATZ SOLOMON
IPC: B64D15/16
Filed: 1995-10-25
Abstract: A movable sheet (22) overlying a wing (20) is disclosed that creates laminar flow over its exposed surface. The movable sheet (22) serves as a shield for protecting a suction support structure (24) of a wing (20) against contamination, and also serves as a movable, conductive substrate (80) for deicing. The invention includes a movable sheet (22) that is mounted scroll-like on two motor-driven rollers (38 and 40). The sheet (22) has a solid area without perforations that protects the suction support structure (24) from contamination, and a porous area (26) with perforations therethrough that allows boundary layer suction. The motor-driven rollers (38 and 40) scroll the sheet (22) to cover the suction support structure (24) with either the solid area or the perforations of the sheet (22). Contact rollers (82) at the edge of the sheet (22) supply electrical current to resistively heat the sheet (22) and melt any accumulated ice. The movable sheet (22) can also be moved back and forth to dislodge the ice.

Title: Resistant exercise shirt and pants
Inventor: DICKER TIMOTHY P
IPC: A41D13/00
Filed: 1996-11-04
Abstract: A resistive exercise suit has a resistive shirt (10) and resistive exercise trousers (12). The resistive exercise shirt (10) uses tension bands (44, 46, 48, 50) on sleeve fronts and backs and attachment to central elastic blocks (40, 42) on the front and back of the shirt. Both the tension bands and the elastic blocks are incorporated into the shirt and provide means by which resistance can be made against arm movements. Thumb stirrups (60, 62) form the sleeve ends and serve as means by which the hands may engage the tension bands (44, 46, 48, 50) and apply resistance against the arms and their muscles. The tension bands may be adjustably attached to the elastic blocks (40, 42). The thumb stirrups may also be adjustable. The resistive exercise trousers fit snugly upon the wearer and have adjustable suspenders and stirrups. The stirrups pass about the feet of the wearer and apply tension to the resistive exercise trousers in conjunction with the adjustable suspenders.

IPC: F04B27/10
Filed: 1997-11-19
Abstract: A compressor housing and method of manufacture and assembly are disclosed.  The compressor housing includes a cylinder block and a front housing.  An annular projection is formed on the front end of the cylinder block. An annular groove is formed on the rear end of the front housing.  The cylinder block and the front housing are secured to each other to prevent the front housing from being displaced in relation to the cylinder block by engaging the annular projection with the annular groove.  A gasket is located between the front end of the cylinder block and the rear end of the front housing secured to each other to seal between the cylinder block and the front housing.  This compressor and its method of manufacture reduce the amount of misalignment between a shaft bore in the cylinder block and a shaft bore in the front housing, which improves the performance of the compressor.
